Abstract:
The present report describes a case of an extrahepatic right hepatic artery pseudoaneurysm caused by acalculous cholecystitis. An 85-year-old man was admitted with abdominal pain, cachexia and jaundice. A CT scan showed a saccular false right hepatic artery aneurysm within a soft tissue and fluid mass that was causing biliary obstruction. The soft tissue mass raised the possibility of malignant disease, but this resolved slowly after a period of time and on reviewing the patient's history the only upper gastrointestinal problem noted was an episode of acalculous cholecystitis 3 months previously, which was believed to be the cause of the pseudoaneurysm. The false aneurysm was treated successfully with coil embolisation and the patient recovered fully from this illness.
